yeah eels are great escape artists i have a 14" fire eel and the first day i got him home he escaped out of a tiny hole at the back of my tank where my filter pipes entered the tank.
The pictures you have provided are not too clear though a little blury the better pic of the 3 would have to be the top one but after looking at the colour of the fish in the other 2 pic's i thought it maybe a ropefish.
You say it looks green like the top pic ! Well in the other 2 it looks brown like a rope fish and the head in the top pic looks like a ropefish's!
I'm not too sure i would suggest you ask TRUST or P45 they seem to know a lot because it's NOT TOO OBVIOUS.
